The frequency of the radio calibration time signal receiving in described step 32 is: 2.5MHZ or 5MHZ or 10MHZ or 15MHZ.
Beneficial effect of the present invention: MIFI clock self checking method disclosed by the invention provides a kind of new technical scheme for the self checking of MIFI clock, can ensure no matter whether to be connected to the verification that 3G or 4G network can round-the-clock MIFI clocks, this MIFI clock self checking method can also be applied in the clock self checking field of other electronic equipments with radio communication function simultaneously.
In this MIFI clock self checking method, adopt radio short-wave signal in addition, this radio short-wave signal is with respect to ratio long wave signal, its signal strength signal intensity is stronger, substantially can ensure that this MIFI terminal equipment can realize without this ratio long wave signal of the reception at network dead angle the inspection of clock signal.
In order further to understand feature of the present invention and technology contents, refer to following about detailed description of the present invention and accompanying drawing, but accompanying drawing only provide with reference to and explanation use, be not used for the present invention to be limited.
Brief description of the drawings
Below in conjunction with accompanying drawing, by the specific embodiment of the present invention is described in detail, will make technical scheme of the present invention and beneficial effect thereof apparent.
In accompanying drawing,
Fig. 1 is MIFI clock self checking method execution step schematic diagram of the present invention;
Fig. 2 is MIFI clock self checking method flow schematic diagram of the present invention.
Embodiment
Technological means and the effect thereof taked for further setting forth the present invention, be described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
For achieving the above object, the embodiment of MIFI clock self checking method provided by the invention is connected to World Wide Web (WWW) at the common 3G of utilization or 4G network, and obtain network calibration time signal thereby to realize time calibration of this MIFI terminal equipment interrupted from World Wide Web (WWW), in can not realizing, the radio calibration time signal that utilizes national time service center to send carries out the verification of time to this MIFI terminal equipment.
The radio calibration time signal of using in MIFI clock self checking method in the present invention is the short-wave signal that the catchword of national time service center transmission is BPM, and its frequency is the one in 2.5MHZ or 5MHZ or 10MHZ or 15MHZ.
With reference to Fig. 1 or Fig. 2, MIFI clock self checking method provided by the invention, comprises the following steps:
